Language selecter and currency converter

hi everyone,

I’m setting up an e-commerce site for a friend using woo commerce.
i know there are many plugins available that will allow customers to change the language, and plugins that will convert the currency, but is there an “all in one” that will do both?

Ideally, the customer selects their location and the language and currency are converted automatically.

I’d also like the currency conversion to be handled via an api maybe to yahoo’s exchange service or something similar. I don’t want him to have to enter the values manually.

Any ides?

Thanks in advance.
Warren
